The `formatTime` function from time-1.4 uses the TimeLocale type from<br>
old-locale, whereas time-1.5 provides its own definition of the TimeLocale<br>
type.  I want to provide `formatTime` with the argument `defaultTimeLocale`.<br>
1.4 requires the version in old-locale whereas 1.5 requires the version it<br>
defines itself.<br>
<br>
Is it possible to use this function in a way that is compatible with both<br>
1.4 and 1.5?  If time-1.5 had merely reexported the old-locale version, and<br>
then (the future) time-1.6 replaced it completely this would have offered a<br>
smoother upgrade path, but as far as I can tell nothing like this was done.<br>
<br>
What are my options?<br>
<br>
Tom<br>
